RESUMEN

INTRODUCTION: There are established protocols for staged return to physical activity in sport and military settings following concussion. Currently, there is no evidence-based staged return to shooting protocol in use by the U.S. military despite the unique challenges and stresses shooting places on the vestibular-ocular and cognitive systems often disrupted by a concussion. The primary purpose of this scoping review was to summarize available evidence and current practices on return to shooting post-concussion, with the goal of optimizing an evidence-based return to shooting protocol for military service members. Our secondary aim was to identify individuals who may benefit from a return to shooting progression. MATERIALS AND METHODS: A comprehensive search of PubMed, SPORTDiscus, and Google Scholar was performed from the earliest dates to April 2023. A gray literature (Google) search was also performed. Articles were included if they studied a population with concussion, addressed return to shooting, and were written in English. Articles were excluded if they discussed health conditions other than concussion, focused on non-shooting interventions, did not use human subjects, or were written in a language other than English. RESULTS: Our search strategy yielded 134 articles: 1 article met our inclusion and exclusion criteria, whereas the other 133 articles were rejected. The gray literature search yielded one item. CONCLUSIONS: Based on our results, there is insufficient evidence to inform current practices on return to shooting post-concussion. In the absence of a published return to shooting protocol, we offer recommendations for identifying individuals who may benefit from a return to shooting progression and a revised version of a U.S. Army Special Operations Command Return to Range Progression. This protocol follows a conceptual framework for progression for variables such as environment, weapon type/caliber, and shooter position/movement. Further research is needed on identifying individuals who may benefit from a return to shooting protocol and safely and effectively progressing these individuals through a return to shooting protocol post-concussion.

RESUMEN

This research aimed to explore cat and dog owners' attitudes and opinions towards various pet care practices in Aotearoa New Zealand (NZ), and determine what factors were associated with them. An online survey composed of both closed and open-ended questions was administered from January to March 2019. A total of 2358 respondents answered the questions on pet care practices. Of these, 37.5 percent (n = 885) were both dog and cat owners, 28.0 percent (n = 652) were cat owners, and 26.0 percent (n = 609) were dog owners, while 9% (n = 212) of respondents did not own a cat or dog at the time of taking the survey. The study revealed that most respondents (>90%) acknowledge the importance of providing adequate housing, regular worming and flea treatments, microchipping, and vaccinations for their pets. Notably, demographic factors such as gender, ethnicity, age range, having children, having a rural upbringing, and place of residence influenced owners' attitudes, with those towards cat care practices varying more than those for dogs. The study highlights the need for responsible pet ownership interventions considering these demographic factors. The study identifies a knowledge gap among pet owners concerning the importance of regular veterinary visits and the impact of breeding for certain looks on animal welfare. The use of shock collar devices provoked varying opinions on their usage for training and behavior modification. The study suggests that enhancing pet owners' knowledge is pivotal for responsible pet ownership. Overall, the findings emphasize the need for tailored interventions that account for demographic variations for promoting responsible pet ownership and animal welfare. The findings underscore the importance of improving access to veterinary health care teams, especially in rural areas, and of providing culturally appropriate education resources for both pet owners and veterinary health care teams.

RESUMEN

This study used an online survey distributed between January and March 2019 to adults residing in Aotearoa New Zealand (NZ) to investigate cat and dog owner practices. Of the 2385 respondents, 885 (37%) owned both cat/s and dog/s, while 652 (28%) and 609 (26%) owned cat/s only or dog/s only, respectively. Nine percent of respondents (n = 212) did not own a cat or dog when the survey was administered. Gaps were identified in the practices of NZ pet owners with regard to regular grooming, immunizations, and deworming treatments. It was also found that many pets, especially cats, were allowed to wander freely both inside and outside the house. Collectively, these gaps in practice raise parasitology and infection concerns which may impact negatively on animal welfare and may increase the prevalence of zoonotic diseases. This study also revealed the need to improve desexing practices, particularly in dogs. Respondents in the survey expressed the wish to have pets regardless of the financial strain they may impose, indicating that future research should focus on reducing the financial burden of pet ownership along with promoting positive pet ownership practices. Our findings suggest the need for better education resources about pet ownership which are easily accessible and target diverse populations. The findings of this study will aid in developing appropriate educational resources to promote animal welfare and increase pet-related knowledge among the NZ populace.

RESUMEN

The primary objective of this study was to compare students' self-assessment ratings with simulated patient (SP) assessment ratings of communication skills in a patient counseling Objective Structured Clinical Exam (OSCE). The secondary objective was to evaluate student perceptions of the importance of communication skills in the practice of pharmacy as well as the impact of a virtual OSCE format. First-year pharmacy students completed an OSCE focused on self-care product counseling. The evaluation was graded using a rubric covering both verbal and non-verbal communication. Students who completed the course were provided a 15-question, post-evaluation survey with questions related to self-assessment of communication skills and perceptions of the importance of communication skills. Of the 138 students in the course, 68 completed the optional post-assessment survey (49% response rate). There were no statistically significant differences between the ratings by students and SPs for the four communication elements included in the self-assessment. Most of the students recognized the importance of communication skills, including developing rapport and trust. Recognition of the importance of communication skills to future practice as a pharmacist positively correlated with performance on the evaluation (r2 = 0.5409, p-value = 0.0007). Student self-assessment is an effective and cost-effective mode of feedback for practice experiences as an alternative to the use of SPs.

RESUMEN

During 2020-2021, countries in Latin America and the Caribbean reported clinical emergence of carbapenemase-producing Enterobacterales that had not been previously characterized locally, increased prevalence of carbapenemases that had previously been detected, and co-production of multiple carbapenemases in some isolates. These increases were likely fueled by changes related to the COVID-19 pandemic, including empirical antibiotic use for potential COVID-19-related bacterial infections and healthcare limitations resulting from the rapid rise in COVID-19 cases. Strengthening antimicrobial resistance surveillance, epidemiologic research, and infection prevention and control programs and antimicrobial stewardship in clinical settings can help prevent emergence and transmission of carbapenemase-producing Enterobacterales.

RESUMEN

Approximately a third of all Aotearoa New Zealand (NZ) households include a dog, with 28% of these dogs being overweight or obese, conditions that are associated with many serious health issues. Therefore, healthy weight interventions that focus on the owner's role are of great importance to companion animal welfare in NZ. Accordingly, the present study explores the feeding practices associated with NZ dogs and identifies potential owner-related risk factors contributing to these animals being overweight or obese. The current study used data collected from a survey conducted online in 2019 between January and March of NZ residents over 18. Along with demographic questions, the respondents were asked questions regarding their dog's body condition and diet questions related to the body. Nearly a quarter (26%, n = 609) of the survey participants (n = 2358) owned at least one dog. The current study reported that increasing age range, household income and the number of children increased the likelihood of having a dog while increasing qualification level and living in a town/city decreased the likelihood. The majority of the respondents fed their dog(s) treats (59%) and 85% fed them specialised food bought from a pet shop, veterinary clinic and/or different online sources. Just over a third of the participant (39%) reported that they fed their dog(s) biscuits from the supermarket, 36% fed their dog(s) raw meat, and 34% of respondents fee their dog(s) table scraps/human food. These results suggest that many dog owners feed their dog(s) various food types, making it a challenging task to determine the exact amount required from each type in order not to exceed caloric intake. Disagreement regarding the correct body condition were reported among twenty per cent of the respondents. This finding indicates a knowledge gap among the NZ dog-owning population that may negatively affect their dogs' welfare and wellbeing. Future research into pro-equity approaches to address these issues is needed so that dogs in NZ can live not only a good life but also their best life.

RESUMEN

Objective: This study's main objective was to analyze the antibiotic susceptibility profile of Escherichia coli isolates obtained from a fecal sample of a captive Baird's tapir (Tapirus bairdii) in Costa Rica. Materials and Methods: The fecal sample was collected inside the enclosure on March 3, 2017, right after the animal defecated. Samples were cultured on MacConkey agar plates nonsupplemented and supplemented with 2 µg/mL of cefotaxime. Bacterial identification and antibiotic susceptibility were performed with the Vitek 2 Compact System and the Kirby Bauer disk diffusion method, respectively. Polymerase chain reaction amplification was performed to detect blaCTX-M beta-lactamase genes. Resistant isolates were subjected to whole-genome sequencing (WGS). Results: After evaluating several antibiotic classes, a multidrug-resistant E. coli strain with extended-spectrum beta-lactamase phenotype was isolated. Resistance to cefotaxime, cefepime, ampicillin, ampicillin/sulbactam, and tetracycline was detected. WGS analysis showed the presence of blaCTX-M-1, blaTEM-1B, and tet(B) genes. The presence of IncN plasmids and Col156 was also detected. Conclusion: Our findings are according with the notion that animals' high density enhances the spread of resistant determinants in a captive environment in a limited space, where the likelihood of direct or indirect contact with other animals and humans is more frequent.

RESUMEN

One in four New Zealand cats are overweight or obese, conditions associated with poor health outcomes. As part of an online survey that was conducted from January 2019 to March 2019, NZ residents aged ≥18 years were asked demographic questions along with questions related to the body condition, breed and diet of their cat/s. From the responses, possible owner-related risk factors for developing obesity were identified. Of the respondents, 65.5% (n = 1537) owned cat/s; the owners being more likely to be female, live rurally, or live with children. Most of the respondents fed their cat/s biscuits from the supermarket (63%) and wet food (57%). Almost half (45%) fed their cat/s specialised food from a pet shop or veterinary clinic and gave them treats, with 31% of respondents feeding their cat/s raw meat. Feeding cats a variety of food types may make it difficult to estimate the appropriate amount of each needed to avoid excess caloric intake. In addition, approximately 30% of the respondents did not agree with the correct body condition statement, revealing a need for owner education. These findings highlight important areas of cat nutrition requiring future research to better inform the development of healthy weight interventions for NZ cats.

RESUMEN

Objective: This study aimed to determine the prevalence of fecal carriage of antibiotic-resistant Escherichia coli of healthy household dogs with an emphasis on extended-spectrum ß-lactamases (ESBL), AmpC-type ß-lactamases and resistance to quinolones. Materials and Methods: Rectal swabs were collected from 74 dogs without any clinical evidence of gastrointestinal disease. Samples were cultured on MacConkey agar plates and MacConkey supplemented with 2 µg/mL cefotaxime or 5 µg/mL ciprofloxacin. Isolates were identified with Vitek 2 Compact and susceptibility testing performed by Kirby Bauer disk diffusion method. Minimal inhibitory concentration (MIC) was done on isolates resistant to cefotaxime, ciprofloxacin, and nalidixic acid. PCR amplification was performed to detect CTX-M and CMY-2. Isolates positive for CTX-M and/or CMY-2 were selected for whole-genome sequencing. Results: Multiresistance was detected in 56% of the isolates. A high percentage of resistance was detected for cefazolin (63%), ampicillin (54%), streptomycin (49%), nalidixic acid (42%) and tetracycline (38%). The MIC50 and MIC90 for isolates resistant to cefotaxime (24%) was determined as 16 and >250 µg/mL, respectively; for ciprofloxacin (18%), 125 and 250 µg/mL, respectively. ESBL (CTX-M type) and AmpC (CMY-2 type) were detected in 6 (7.1%) and 14 (19%) of the isolates, respectively. Whole-genome sequence analysis showed high genetic diversity in most of the isolates and a large variety of resistance mechanisms, including mobile genetic elements. Conclusion: The frequency of multidrug-resistant E. coli is worrying, mainly because of the presence of many isolates producing ESBL and AmpC ß-lactamases. Based on the "One Health" concept, considering the relationships between animals, humans, and the environment, these data support the notion that companion animals are important reservoirs of multidrug-resistant bacteria.

RESUMEN

Aims: This study aimed to investigate the experiences of registered prescribers and their perceptions of the enablers and barriers to registered prescribing and the value of this fledgling role. Background: The role of prescribing has been extended to registered nurses in New Zealand. By adding the designated prescribing role to a nurse's role, their scope of practice expands and nurses are able to provide patients with holistic care while achieving greater independence and role satisfaction. Yet new nurse prescribers can experience anxiety and fear when confronted with the reality of the responsibility of prescribing. Methods: Sixteen semi-structured interviews were conducted with registered nurse prescribers across New Zealand. Data were analysed using a general inductive approach and thematic analysis utilised to identify themes and sub-themes. Results: Sixteen registered nurse prescribers participated in the study. Three main themes emerged with sub-themes: ability to expand practice, improving access to care, and importance of working in a collaborative team. Participants explained how they enjoyed the challenge and responsibility of the new prescribing role yet were frustrated with the realities of the restrictions of what they could actually prescribe and in some cases lack of role recognition. Registered nurse prescribing also improved access to care as nurses felt they provided more comprehensive care, resulting in reduced wait times, better continuity of care and a reduction in patient costs. The participants highlighted the importance of working in a collaborative team and believed their ability to prescribe maximised clinician time, however cautioned the need for on-going clinical mentorship and a prepared and supportive work environment. Conclusions: The addition of registered nurse prescribing provides a number of advantages to individual nurses in terms of career development and job satisfaction, and to patients and the health care system. The benefits to health care consumers and the health care system align directly to health care priorities of improving equity and access to care. Impact statement: Registered nurse prescribers perceive a number of advantages to the addition of prescribing to their own practice and benefits to patients and the health care system by enabling more accessible and cost-effective care.

RESUMEN

AIMS: This paper describes findings from a survey conducted in New Zealand exploring nurses' decision-making about when to delay care, delegate care, hand care over or leave care undone. Unanticipated findings identified processes that nurses go through when deciding to take planned/unplanned leave when wards are constrained through budget limitations. BACKGROUND: Missed/rationed care is increasingly the focus of attention in international studies, identifying a complex interplay of organisational, professional and personal factors affecting nurses' decision-making when faced with limited organisational time, human and material resources to provide care. METHODS: The survey presented nurses with Likert-scale questions with option for free text comments. This paper reports on the commentaries about work-life balance. RESULTS: Nurses described workload pressures that lead to rationing care affected them, and the long-term effect on them as individuals. Nurses verbalized the difficulties and associated guilt about taking leaving and sick leave when wards were short staffed. CONCLUSIONS: Nurses consider how their absence will affect the workspace and their home first, considering the impact on themselves last. IMPLICATIONS: The findings may provide valuable insights for nurse managers in relation to workforce allocations and resources where acknowledgement of work-life balance is considered.

RESUMEN

This document presents a Latin American consensus to standardize definitions of different levels of antimicrobial resistance in bacteria of public health importance. Inclusion and exclusion criteria are described for antibiotics to include (availability, relevance, and existence of cut-off values) and for methodologies to use. Three gram-negative microorganisms with a great impact in the hospital environment (Klebsiella pneumoniae, Pseudomonas aeruginosa, and Acinetobacter spp.) were selected as a pilot proposal. The lack of cut-off values for certain antibiotics (e.g., tigecycline, fosfomycin, and colistin), crucial in treating infections caused by multi-drug resistant or extensively drug-resistant pathogens, led to the need to discuss and agree on provisional cut-off values for monitoring resistance to these drugs. The work team also addressed and reached consensus on easier-to-use alternative susceptibility tests, other than methods approved by international guidelines, for routine testing in clinical bacteriology laboratories. The main benefit of this document is to provide Latin American laboratories with a standardized and consensual framework for the identification and constant and unified surveillance of resistant microorganisms. The recommendations included in this document are the result of consensus among representatives of the national reference laboratories in the countries belonging to the Latin American Surveillance Network of Antimicrobial Resistance, coordinated by the Pan American Health Organization.


É apresentado um consenso latino-americano para padronizar a definição dos graus de resistência antimicrobiana em bactérias de importância em saúde pública. São descritos os critérios de inclusão e exclusão para os antibióticos a serem incluídos (disponibilidade, relevância e pontos de corte de sensibilidade) e metodologias a serem usadas. Como proposta-piloto, foram selecionados três microrganismos Gram-negativos de grande impacto no ambiente hospitalar (Klebsiella pneumoniae, Pseudomonas aeruginosa e Acinetobacter spp.). Diante da falta de pontos de corte para alguns antibióticos (como tigeciclina, fosfomicina e colistina), essenciais para o tratamento de infecções causadas por patógenos com multirresistência ou resistência ampliada, foram debatidos e aprovados pela maioria pontos de corte provisórios para a vigilância da resistência a estes fármacos. Também foi discutido e aprovado o uso de testes de suscetibilidade alternativos aos métodos aprovados pelas diretrizes internacionais, mais simples de serem realizados como testes de rotina nos laboratórios de bacteriologia clínica. A principal contribuição deste documento é oferecer aos laboratórios latino-americanos um sistema padronizado e consensual para a identificação de microrganismos resistentes e a vigilância contínua e uniforme destes patógenos. As recomendações aqui contidas foram feitas por consenso por representantes dos laboratórios nacionais de referência dos países que integram a Rede Latino-Americana de Vigilância da Resistência Antimicrobiana, coordenada pela Organização Pan-Americana da Saúde (OPAS).

RESUMEN

Purpose The purpose of this paper is to explore how nurses make decisions to ration care or leave it undone within a clinical environment that is controlled by systems level cost containment. The authors wanted to find out what professional, personal and organisational factors contribute to that decision-making process. This work follows previous international research that explored missed nursing care using Kalisch and Williams' MISSCARE survey. Design/methodology/approach The authors drew on the care elements used by Kalisch and Williams, asking nurses to tell us how they decided what care to leave out, the conduits for which could include delaying care during a shift, delegating care to another health professional on the same shift, handing care over to staff on the next shift or leaving care undone. Findings The findings suggest that nurses do not readily consider their accountability when deciding what care to leave or delay, instead their priorities focus on the patient and the organisation, the outcomes for which are frequently achieved by completing work after a shift. Originality/value The actions of nurses implicitly rationing care is largely hidden from view, the consequences for which potentially have far reaching effects to the nurses and the patients. This paper raised awareness to hidden issues facing nurses within a cycle of implicitly rationing care, caught between wanting to provide care to their patients, meeting the organisation's directives and ensuring professional safety. Rethinking how care is measured to reflect its unpredictable nature is essential.

RESUMEN

This article examines nurses' commentaries from a survey conducted in New Zealand that studied contradictions between quality assurance and work intensification in nursing care. Nurse managers were blamed for either avoiding or not recognizing work intensification affecting quality care delivery. However, the data illustrate key structural issues resulting in missed care that impact on patient safety, rather than a problem directly attributable to managers. Until these structural issues are addressed, missed care and adverse events will continue to affect the quality of care.

RESUMEN

AIMS: To outline the way the culture of austerity arising from the Global Financial Crisis has been used by Australian and New Zealand governments to maintain and extend healthcare budget cuts, through new public management strategies leading to missed nursing care. BACKGROUND: Ten years on the cost of the Global Financial Crisis continues to be borne by tax payers and those employed by the welfare state, yet analysis shows clearly that it was caused by a failure to adequately regulate markets, particularly the banks and multinational corporations. In health care, one of the impacts is increased workload for nurses leading to missed care. DESIGN/METHODS: Registered Nurses and midwives (n = 7,302) completed the MISSCARE surveys between 2012 - 2015, in four Australian states and New Zealand providing quantitative and qualitative responses. The qualitative comments were analysed using a template analysis approach based on key features of New Public Management. FINDINGS: Sixty-two qualitative responses identified measures in place directly linked to austerity and new public management strategies that impacted on the quality of patient care and nursing work, as well as contributing to missed care. CONCLUSION: Opportunities for resistance may lie outside public and private health organizations in civil society, in the nurse union movements and other health and nursing professional associations.

RESUMEN

This article draws on the free-text commentaries from trans-Tasman studies that used the MISSCARE questionnaire to explore the reasons why nurses miss care. In this paper, we examine the idea that nurses perpetuate a self-effacing approach to care, at the expense of patient care and professional accountability, using what they describe as the art of nursing to frame their claims of both nursing care and missed nursing care. We use historical dialogue alongside a paradigmatic analysis to examine why nurses allow themselves to continue working within settings that put their professional/personal selves aside in an attempt to deliver care within constraints that make completing care an impossible task. The findings suggest an ambivalence and conflict confront nurses attempting to provide care within the New Public Management environment. This can be seen in the tensions that draw a line between care as an art, and care as a financial target, juxtaposed with the inherent clash of values arising from the way nursing care is conceptualised within two contradictory paradigms.

RESUMEN

It is well established that motility is an essential virulence trait of the human gastric pathogen Helicobacter pylori. Accordingly, chemotaxis contributes to the ability of H. pylori to colonize animal infection models. Chemotactic signal transduction in H. pylori differs from the enterobacterial paradigm in several respects. In addition to a separate CheY response regulator protein (CheY1), H. pylori contains a CheY-like receiver domain (CheY2) which is C-terminally fused to the histidine kinase CheA. Furthermore, the genome of H. pylori encodes three CheV proteins consisting of an N-terminal CheW-like domain and a C-terminal receiver domain, while there are no orthologues of the chemotaxis genes cheB, cheR and cheZ. To obtain insight into the mechanisms controlling the chemotactic response of H. pylori, we investigated the phosphotransfer reactions between the purified two-component signalling modules in vitro. We demonstrate that both CheY1 and CheY2 are phosphorylated by CheA approximately P and that the three CheV proteins mediate the dephosphorylation of CheA approximately P, but with a clearly reduced efficiency as compared to CheY1 and CheY2. Furthermore, our data indicate retrophosphorylation of CheAY2 by CheY1 approximately P, suggesting a role of CheY2 as a phosphate sink to modulate the half-life of CheY1 approximately P.

RESUMEN

Flagellar motility is essential for the ability of Helicobacter pylori to colonize the gastric mucosa. Expression of the flagella is controlled by a complex regulatory cascade involving the two-component system FlgR-HP244, the sigma factors sigma54 and sigma28 and the anti-sigma28 factor FlgM. The protein-protein interaction map of H. pylori, which is based on a high-throughput two-hybrid screen (Rain et al., 2001. Nature 409, 211-215) indicated a protein-protein interaction between the gene product of ORF hp137 and both the histidine kinase HP244 and the flagellar hook protein HP908. We hypothesized that HP137 might be involved in a feedback regulatory mechanism controlling the activity of histidine kinase HP244. Here we demonstrate that HP137 does not participate in the regulation of flagellar gene expression, neither in H. pylori nor in the closely related bacterium Campylobacter jejuni.
